ABSTRACT

A data transmission system for transmitting an electrical data to a nerve cell. A data receiving system for receiving an electrical data from a nerve cell has at least two phototransistor crystals that is stimulated by light to form an electrical signal; an image source that allows the light to be sent to the phototransistor crystals and allows controlling the amount of light transmitted to each phototransistor crystal independently of each other, and at least one control unit that is connected to the image source that controls the amount of light transmitted from the image source to each of the phototransistor crystals.

TECHNICAL FIELD

The present invention relates to data communication systems that allow, for example, to receive an electrical data from a nerve cell and to transmit the electrical data to the nerve cell.

PRIOR ART

In a human body, data communication between the brain, spinal cord and other organs is achieved through nerve cells. The data received from the organs and the data transmitted to the organs are usually in the form of electrical signals. In addition, the data communication between the nerve cells is performed electrically or chemically.

Since the communication between the nerves and the organs is provided by electrical signals, it is also possible to transmit data from outside by nerves. For instance, in case of a person with limb loss, electrical signals can be transmitted to the nerve cells associated with the lost limb so as to mimic the data that should have been received from the lost limb. In this manner, for example, certain data from the prosthesis used by a patient suffering from hand loss can be transmitted to his brain through the patient's nerves.

In the known art, electrodes that are connected to nerve cells are used to transmit electrical signals to the nerve cells. However, since the nerve cells have very sensitive structures, the electrical signals sent to the nerve cell must be controlled very precisely. If the signal sent to the nerve cell has a relatively high voltage and/or current value, the nerve cell may get damaged whereby a high degree of pain may be felt. Furthermore, for example the need for individually controlling the electrical signal sent to each of the electrodes so as to send separate signals to a plurality of nerve cells, causes such systems to have complex, costly and large structures.

BRIEF DESCRIPTION OF THE INVENTION

With the present invention, there is provided a data transmission system that allows transmitting an electrical data to a target, and a data receiving system that allows receiving an electrical data from a target. Said data transmission system comprises at least two phototransistor crystals, each of which is stimulated by light, to form an electrical signal; at least one image source which allows the light to be sent to said phototransistor crystals and allows controlling the amount of light transmitted to each phototransistor crystal independently of each other; and at least one control unit which is connected to said image source and controls the amount of light transmitted from the image source to each of the phototransistor crystals. Each phototransistor crystal comprises at least one signal output at which electrical signal is generated and which is coupled to the target to which the generated electrical signal is to be transmitted; at least one voltage input common terminal; and at least one threshold light intensity control input which allows controlling the level of the electrical signal generated at the signal output according to the amount of light received.

In the data transmission system according to the present invention, since an electrical signal is transmitted through the phototransistor crystal to a target such as a nerve cell, it is guaranteed that the transmitted electrical signal never exceeds a maximum value.

Similarly, in the data receiving system according to the present invention, thanks to using a large number of light crystals and image sensors, it is ensured that the electrical signal received from a plurality of targets is detected independently from each other.

DESCRIPTION OF THE INVENTION

In the cases of patients with limb loss, the nerve cells associated with said limb usually remain active. By using the active-remaining nerve cells, electrical signals can be sent to and/or received from the patient's brain. Therefore, with the present invention, there is provided a data transmission system which allows transmitting an electrical data to a target such as a nerve cell, and a data receiving system which allows receiving an electrical data from a target such as a nerve cell.

The data transmission system according to the present invention, as illustrated in FIGS. 1-3 , comprises at least two phototransistor crystals (T) which are stimulated by light (l) to form an electrical signal; at least one image source (4) (for example, LCD panel, OLED panel, screen etc.) which allows the light (l) to be sent to said phototransistor crystals (T) and allows controlling the amount of light (l) transmitted to each phototransistor crystal (T) independently of each other; and at least one control unit (not illustrated in Figures) which is connected to said image source (4) and controls the amount of light (l) transmitted from the image source (4) to each of the phototransistor crystals (T). Said phototransistor crystal (T) comprises at least one signal output (1) at which electrical signal is generated and which is coupled to the target to which the generated electrical signal is to be transmitted; at least one voltage input common terminal (3); and at least one threshold light intensity control input (2) which allows controlling the level of the electrical signal generated at the signal output (1) according to the amount of light (l) received. According to the invention, each pixel of the image source (4) serves as a separate light source. Here, since the image source (4) is able to transmit the light (l) individually to each phototransistor crystal (T), it is ensured that the electrical signal received from each phototransistor crystal (T) can be individually controlled in real time. Said image source (4) may have a structure that emits visible light (l), or may have a structure that emits the light (l) at an invisible frequency such as infrared or ultraviolet.

In an exemplary embodiment of the data transmission system, said phototransistor crystal (T) has a structure of an NPN or PNP transistor. The signal output (1) (N or P terminal) is connected to at least one nerve cell (N) as shown in FIG. 3 . Said signal output (1) preferably comprises at least one first conductive part (1 a), thereby it can be connected to the target easily so as to be able to transmit the electrical signals to the target. Here, the light (l) is transmitted onto the phototransistor crystal (T) by means of the image source (4) according to the data received from at least one data input (21) connecting the control unit and the image source (4) to each other. An electrical signal relative to the amount of transmitted light (l) is generated at the signal output (1), and the generated signal is transmitted to the nerve cell (N). In this manner, it is ensured that a desired electrical signal is sent to the nerve cell (N). Here, by virtue of controlling the brightness of the image source (4) by means of the control unit, the amount of light (l) falling on the phototransistor crystal (T) and thus the level of the electrical signal obtained at the signal output (1) are controlled. In this way, it is ensured that the signal transmitted to the nerve cell (N) is controlled. Thanks to a control signal sent from said threshold light intensity control input (2) (P or N terminal), the minimum values of the signal to be obtained at the signal output (1) can be controlled. Thus, for example, it is ensured that a signal is not obtained at the signal output (1) when the level of the light (l) received from the image source (4) is below a certain threshold value, whereas a signal is obtained at the signal output (1) when the level of the light (l) rises above said threshold value.

In a preferred embodiment of the invention, the data transmission system comprises at least one body (6) in which at least one phototransistor crystal (T) is positioned. Said body (6) is preferably in the form of an insulating gel. In this embodiment, the body (6) serves as an insulating layer to prevent the short circuit of the system and the damage of the phototransistor crystal (T) from environmental factors. In a preferred embodiment, said body (6) comprises at least one upper cover (7) for an easy connection of the phototransistor crystal (T) to a target. In an exemplary embodiment, said upper cover (7) is coupled to a sheath (M) (for example fascicle) located outside the nerve cell (N) so as to ensure that the nerve cell (N) is attached to the phototransistor crystal (T) in a firm and reliable manner. Said body (6) further comprises at least a second conductive part (8) connected with the threshold light intensity control input (2) so as to be able to send said control signal at the threshold light intensity control input (2). In another preferred embodiment, the body (6) comprises at least one lower cover (10) located on the side of the phototransistor crystal (T) that faces the image source (4). Said lower cover (10) has a transparent (light (l) transmitting) structure, which allows the light (l) rays coming from the image source (4) to reach the phototransistor crystal (T). In another preferred embodiment, the data transmission system comprises at least a third conductive part (9) to which the voltage input common terminal (3) of different phototransistor crystals (T) is connected.

The first conductive part (1 a), the second conductive part (8) and the third conductive part (9) used in the system may be made of either conductive (zero electrical resistance) materials or the materials with an individual constant electrical resistance. In the alternative embodiments of the invention, by using conductors that have different electrical resistance values (R1, R2, R3) for the first conductive part (1 a), the second conductive part (8) and the third conductive part (9), gain control of the phototransistor crystal (T) is able to be performed, the output voltage value is able to be controlled and/or limited to a fixed upper value. Furthermore, by using phototransistor crystals (T) made of different semiconductors (SiN, GeP etc.), maximum current and voltage limits required for the system can be achieved.

A circuit diagram of the data transmission system according to the present invention is shown in FIG. 2 . Here, the signal obtained at the signal output (1) is indicated as V1, and the control signal sent to the threshold light intensity control input (2) is indicated as V2. The resistances indicated by R1, R2, R3 are the electrical resistance values of the first conductive part (1 a), the second conductive part (8) and the third conductive part (9), respectively. Depending on the polarity of the signal generated in the embodiment (whether the phototransistor crystal (T) is NPN or PNP), the voltage V1 has a negative or positive polarity. Therefore, the polarity of the voltages that complete the circuit also changes according to the output polarity of the system. For this reason, instead of using the (+) or (−) sign in the electrical schemes, the voltage itself and its opposite (with reverse polarity) are shown. Those shown as overlined are “THE OPPOSITE” of the relevant voltages. In other words, if the polarity of Voltage V1 is Positive (+), its opposite is represented by the Negative (−) polarity. If the polarity of Voltage V1 is Negative (−), the opposite of V1 is represented by the Positive (+) polarity.

In a preferred embodiment of the invention, the data transmission system further comprises at least one optical element (5) disposed between the image source (4) and phototransistor crystals (T). Said optical element (5) preferably enables to match the phototransistor crystal (T) with the pixels of the image source.

In an exemplary embodiment of the invention, said data transmission system is used together with a tactile sensor (for example, a tactile sensor as explained in the patent document no. WO2014011126A1). In this embodiment, the control unit controls at what level the light (l) is to be sent to which phototransistor crystal (T) according to the tactile information (tactile position, intensity etc.) received from the touch sensor. Thus, the intensity and position of a touch via a prosthetic limb is, for example, able to be transmitted to the brain by means of the data transmission system developed in accordance with the present invention.

The control unit according to the invention can receive, by means of any wired or wireless data transfer method, the information concerning at what level the light (l) is to be sent to which phototransistor crystal (T). Thus, data is able to be sent to the brain of a person, to whom the invention is applied, either by means of the sensors of artificial devices such as prosthesis etc, attached on the person or by connecting with a remote device.

Although the data transmission system developed by the present invention is used for transmitting data to the nerve cells (N) in the examples hereinabove, the usage area of the data transmission system is not limited to only nerve cells (N). According to the data transmission system of the present invention, said data transmission system is able to be used in all the data transmission systems which require sensitive data transmission, since the level of the electrical signal received from the signal output (1) of the phototransistor crystal (T) (voltage value) is always below a maximum voltage value. Furthermore, in the embodiment wherein the data transmission system comprises a plurality of phototransistor crystals (T), the data transmission system developed by the present invention also provides a multi-channel data transmission, since the electrical signal received from each phototransistor crystal (T) can be individually controlled.

The electrical signals carried by the nerve cells (N) are transmitted as pulse width modulation (PWM) signal. In other words, the voltage value of the electrical signals carried by the nerve cells (N) is constant, and the frequency of the signal changes. Thus, in the embodiments wherein the data transmission system developed by the present invention is used particularly with the nerve cells (N), the electrical signal received from the signal output (1) of the phototransistor crystal (T) is also in the form of a PWM signal. In this embodiment, said control unit is also configured to control the frequency (flashing frequency) as well as the brightness level of the image source (4). Thus, it is ensured that the electrical signal received from the signal output (1) is controlled. In an exemplary embodiment, the brightness level of the light sent to each phototransistor crystal (T) is the same and by changing the flashing frequency of the light, the pulse width modulation of the electrical signal obtained from the each phototransistor crystal (T) is able to be controlled.

In another preferred embodiment of the invention, instead of matching each pixel of said image source (4) with a phototransistor crystal (T), a phototransistor crystal (T) is matched with more than one pixels. Thus, the amount of light (l) sent to the phototransistor crystal (T) can be increased and/or controlled more precisely.

In another preferred embodiment of the invention, said phototransistor crystal (T) has a structure of a phototransistor. Thus, it is made possible that the currently available phototransistors are used in the data transmission system of the present invention.

The data receiving system according to the present invention, as illustrated in FIGS. 4-6 , comprises at least two light crystals (P), each of which is connected to at least one target and emits light (l) by means of an electric signal received from the corresponding target; at least one image sensor (14) (for example, CMOS, CCD etc.) for detecting the light emitted by each light crystal (P) independently of each other; and at least one control unit (not shown in figures), to which said image sensor (14) is connected and to which the image generated by the image sensor (14) is transmitted preferably by means of at least two data outputs (22). Said light crystal (P) comprises at least one signal input (11) to which said target is connected and which receives the electrical signal received from the target; at least one threshold signal voltage control input (12) which allows controlling the minimum value and level (brightness) of the light generated in the light crystal (P) according to the electrical signal received from the signal input (11); and at least one voltage input common terminal (13). Said light crystal (P) may preferably have a structure, (for example a LED structure), that emits visible or invisible light (l) (such as infrared or ultraviolet). Here, it is ensured that the light (l) emitted by each light crystal (P) can be individually detected in real time since the light (l) emitted by each light crystal (P) is detected individually by the image sensor (14).

In an exemplary embodiment of said data receiving system, the light crystal (P) basically has a structure of an NPN or PNP crystal (LED). The signal input (11) (N or P terminal) is connected to at least one nerve cell (N) as shown in FIG. 6 . Said signal input (11) preferably comprises at least one first conductive part (11 a), thereby it can be connected to the target easily so as to be able to transmit the electrical signals to the target. Here, light (l) is generated in the light crystal (P) by means of an electrical signal coming from the nerve cell (N). Since the generated light is detected by the image sensor (14), the characteristics of the signal coming from the nerve cell (N) are able to be obtained by the image sensor (14). Thanks to a control signal sent from said threshold signal voltage control input (12) (P or N terminal), maximum and minimum values of the brightness of the light which is to be obtained in the light crystal (P) can be controlled. Thus, for example, it is ensured that no light is obtained in the light crystal (P) when the electrical signal received from the nerve cell (N) is below a certain threshold value, whereas a light is obtained in the light crystal (P) when the electrical signal rises above said threshold value.

In another preferred embodiment of the invention, the data receiving system comprises at least one body (16) in which at least one light crystal (P) is positioned. Said body (16) is preferably in the form of an insulating gel. In this embodiment, the body (16) serves as an insulating layer to prevent the short circuit of the system and the damage of the light crystal (P) from environmental factors. In a preferred embodiment, said body (16) comprises at least one upper cover (17) for an easy connection of the light crystal (P) to a target. In an exemplary embodiment, said upper cover (17) is coupled to a sheath (M) (for example fascicle) located outside the nerve cell (N) so as to ensure that the nerve cell (N) is attached to the light crystal (P) in a firm and reliable manner. Said body (16) further comprises at least a second conductive part (18) connected with the threshold signal voltage control input (12) so as to be able to send said control signal at the threshold signal voltage control input (12). In another preferred embodiment, the body (16) comprises at least one lower cover (20) located on the side of the light crystal (P) that faces the image sensor (14). Said lower cover (20) has a transparent (light (l) transmitting) structure, which allows the light (l) rays coming from the light crystal (P) to reach the image sensor (14). In another preferred embodiment, the data receiving system comprises at least a third conductive part (19) to which the voltage input common terminal (13) of different light crystals (P) is connected.

The first conductive part (11 a), the second conductive part (18) and the third conductive part (19) used in the system may be made of either conductive materials (zero electrical resistance) or the materials with an individual constant electrical resistance. In the alternative embodiments of the invention, by using conductors that have different electrical resistance values (R1, R2, R3) for the first conductive part (11 a), the second conductive part (18) and the third conductive part (19), gain control of the phototransistor is able to be performed and the output voltage value is able to be controlled and or limited to a fixed upper value. Furthermore, by using light crystals (P) made of different semiconductors (Si, GaSb, GaAs, SiGe etc.), current and voltage limits required for the system can be achieved.

A circuit diagram of the data receiving system according to the present invention is shown in FIG. 5 . Here, the signal coming to the signal input (11) is indicated as V1, and the control voltage sent to the threshold signal voltage control input (12) is indicated as V2. The resistances indicated by R1, R2, R3 are the electrical resistance values of the first conductive part (11 a), the second conductive part (18) and the third conductive part (19), respectively. Depending on the polarity of the signal generated in the embodiment (whether the light crystal (P) is NPN or PNP), the voltage V1 has a negative or positive polarity. Therefore, the polarity of the voltages that complete the circuit also changes according to the output polarity of the system. For this reason, instead of using the (+) or (−) sign in the electrical schemes, the voltage itself and its opposite (with reverse polarity) are shown. Those shown as overlined are “THE OPPOSITE” of the relevant voltages. In other words, if the polarity of Voltage V1 is Positive (+), its opposite is represented by the Negative (−) polarity. If the polarity of Voltage V1 is Negative (−), the opposite of V1 is represented by the Positive (+) polarity.

In a preferred embodiment of the invention, the data receiving system further comprises at least one optical element (15) disposed between the image sensor (14) and light crystal (P). Said optical element (15) preferably enables to match the light crystal (P) with the pixels of the image sensor.

In another preferred embodiment of the invention, instead of matching each pixel of said image sensor (14) with a light crystal (P), a light crystal (P) is matched with more than one pixels. Thus, the amount of light (l) sent to the image sensor (14) can be increased and/or controlled more precisely.

Although the data receiving system developed by the present invention is used for receiving data from the nerve cells (N) in the examples hereinabove, the usage area of the data receiving system is not limited to only nerve cells (N). In the embodiment wherein the data receiving system of the present invention comprises a plurality of light crystals (P), the data receiving system developed by the present invention also provides a multi-channel data transmission, since the light (l) emitted by each light crystal (P) can be individually detected.

The electrical signals carried by the nerve cells (N) are transmitted as pulse width modulation (PWM) signal. In other words, the voltage value of the electrical signals carried by the nerve cells (N) is constant, and the frequency of the signal changes. Thus, in the embodiments wherein the data receiving system developed by the present invention is used particularly with the nerve cells (N), a light (l) which has a constant brightness but a variable frequency, and emitted by the light crystal (P) is obtained. Furthermore, the information of the signal received from the nerve cell (N) is obtained according to the frequency change amount of the light.

In an exemplary embodiment, the data transmission system and the data receiving system of the present invention can be used together. The connection therebetween can be in the form of a wired or wireless communication. In this embodiment, for example, when a neural disconnection occurs between the brain and an organ of a patient, the nerve cell ending connected to the brain is attached to the data receiving system so that the electrical signal coming from the brain is detected. By attaching the nerve cell ending that is connected to the organ to the data transmission system and sending the electrical signal detected by the data receiving system to the data transmission system, it is ensured that a command coming from the brain is sent to the organ.

In another exemplary embodiment, a nerve cell (N) may be in connection with both the data transmission system and the data receiving system. In this embodiment, said nerve cell (N) is connected not only to the signal input (11) of the light crystal (P) but also to the signal output (1) of the phototransistor crystal (T). Here, since both the signal input (11) of the light crystal (P) and the signal output (1) of the phototransistor crystal (T) are interconnected through the nerve cell (N), the electrical signal obtained at the signal output (1) of the phototransistor crystal (T) stimulates the light crystal (P) as well. Thus, in this embodiment, the control unit in the data receiving system and the control unit in the data transmission system are in connection with each other, and for detecting a signal received from the nerve cell (N) in the data receiving system, the electrical signal sent to the nerve cell (N) by the data transmission system is also taken into account. In this embodiment, bilateral data transmission (both receiving and transmitting data) can be achieved with the nerve cells (N). In the embodiment where a connection is established with a plurality of nerve cells (N), a plurality of light carriers (for example a fiber optic cable) can be used in matching each light crystal (P) with a pixel of the image sensor and in matching each phototransistor crystal (T) with a pixel of a LCD panel. Here, while a first fiber optic cable harness allows light (l) transmission between the light crystals (P) and the image sensor, a second fiber optic cable harness allows light (l) transmission between the phototransistors (T) and the LCD panel.

In the data transmission system and the data receiving system according to the present invention, energy levels of the received and the transmitted data are able to be controlled by said control units. Thus, for example in case of an application of a prosthetic limb which uses the data transmission system, the intensity of a detected touch is able to be transmitted to the nerve cell (N) by increasing, decreasing, locally turning on or turning off, and/or applying various filters by the control unit. In this manner, the user's feeling sensitivity can be increased or decreased. In another exemplary embodiment, a weak signal, for example due to a nerve damage, received from a nerve cell (N), can be increased by the control unit in the data receiving system so that it can be perceived more strongly. Thus, it is ensured that the data receiving system can also be used in the persons with neural disorders.

Thanks to the data receiving system of the present invention, it is ensured that the electrical signals carried by different nerve cells (N) in the body can be easily transferred to a computer or processor, saved and analyzed. Thus, for example, by comparing the data obtained from healthy individuals and individuals with specific diseases, the cause of the related diseases can be understood. Furthermore, by analyzing the electrical signals, many mysteries related to the brain and nervous system can also be cleared up.

With the data receiving and transmission system of the present invention, nerve impulses required for stimulating the organs can be artificially sent to these organs, or the signal sent can be detected and transmitted in any desired form. For example, by sending signals to beta cells in pancreas, insulin secretion can be achieved.

In addition, for example signals carried by certain nerves can be saved and, where necessary, the saved data can be transmitted to the nerve cells (N) by using the data transmission system developed by the present invention. In an exemplary embodiment, feelings such as touching, jarring, moving in a movie can be artificially transmitted to viewers by being recorded during shooting a film or added later. For example, the electrical signals generated in the nerve cells (N) by smelling can be copied and artificially presented to the individuals so that the smell is able to be transmitted digitally.

The data receiving system and the data transmission system according to the present invention can be used for transfer of analog voltage, digital I/O signal, PWM signal, the signals in CAN BUS or in any other communication protocol.

In the data transmission system according to the present invention, since an electrical signal is transmitted through the phototransistor crystal (T) to a target such as a nerve cell (N), it is guaranteed that the transmitted electrical signal never exceeds a maximum value. Furthermore, by using a large number of phototransistor crystals (T) and LCD panels, it is ensured that an electrical signal is sent individually to a plurality of targets. Similarly, in the data receiving system according to the present invention, thanks to using a large number of light crystals (P) and image sensors, it is ensured that the electrical signal received from a plurality of targets is detected independently from each other. According to the data transmission system and the data receiving system of the present invention, the signal threshold value is also allowed to be able to be controlled by means of the threshold light intensity control input (2) and the threshold signal voltage control input (12). Moreover, in the embodiments where the data transmission system and/or the data receiving system comprises the upper cover (7, 17), the upper cover (7, 17) is fixed to nerve endings by micro-surgery with adhesion or a similar method. In the same way, it can be applied to the nerves of healthy individuals by means of the invention, therefrom it is made possible to send signals to their brain and/or receive the signals from their brain.
